Automatically generating a reference mark in virtual shared space

A method comprising:

• detecting movement of a first avatar on one of a plurality of computers connected to a computer server;
• marking an object pointed to by the first avatar with a reference marker in a virtual reality space;
• and
• storing creation time of the reference marker, information about one of the object on which the reference marker is to be put, movement information about the movement of the first avatar, and avatar information about the first avatar;
• generating the reference marker based on the movement information about the movement of the first avatar;
• guiding a second avatar on one of the plurality of computers to the object pointed to by the first avatar in response to a user's selecting on a screen display a notification of the presence of the reference marker;
• registering a policy in advance to the computer server by one of the plurality of computers, the policy defining a reference marker whose presence the one of the plurality of computers wishes to be notified of;
• selecting the generated reference marker if the generated reference marker meets the policy, and notifying the plurality of computers of the presence of the selected reference marker;
• acquiring from one of the plurality of computers a selection operation which one of the plurality of computers performs in response to a reference marker notification displayed on a display screen;
• and
• updating positional information and line information on a second avatar to guide the second avatar to the selected reference marker.
